Scientific Forming Technologies Corporation (SFTC) is currently looking for several self-motivated and talented individuals to further develop its Finite Element based software product DEFORM™. Please visit www.deform.com for more details. Ph.D in Engineering with strong background in mechanics, and/or manufacturing processes, and programming experience (FORTRAN under Windows or UNIX environment), and excellent problem solving skills are highly desirable.
Tony Evans passed away on Wednesday after a long and valiant fight against cancer. He was Alcoa Professor of Materials, Professor of Mechanical Engineering and Director of the Center for Multifunctional Materials and Structures at the University of California at Santa Barbara.
A fully funded PhD research studentship is available at the University of Oxford, in the Solid Mechanics Group.

Call for Abstracts
Unlike other blog-posts of mine, I am not going "own" this particular thread. By that, I mean to say: I am going to only begin this thread and immediately turn it over to you completely. I am not going to watch over whether the discussion here continues to stick to its main theme or not, whether it slides into some minor side issues, whether it deserts the main theme altogether, etc., the way I usually do.

This thread is meant to be about the following book:
It seems that the measurment of local stress and strain in fatigue crack tip will be difficult. some researcher use F.E analysis method,in contrary using of numerical solution. however analytical method also has investigated. what method you can imagine? i need a brain storm in this issue.
Thank you
Hadi
Dear Colleagues,
May I have your attention please? It's air time for the second episode of "Popular Science's Future of...Combat". The show will air on The Science Channel (science.discovery.com) at 9pm ET/PT on 9/07/09. The research on biological armors by Christine Ortiz's group from MIT will be reported.
Enjoy.
What is the difference between Eulerian and Lagrangian coordinates?
I have read that, Eulerian coordinates correspond to spatial points and Lagrangian correspond to material points.
A material point corresponds to a spatial coordinate in initial configuration?
I'm , however, not able to get the diference between the two.Can anyone explain?
In conventional linear finite element analysis, what do we use?Lagrangian or Eulerian mesh?
We perform uniaxial tensile tests on polyimide-supported copper films with a strong (111) fiber texture and with thicknesses varying from 50 nm to 1 μm. Films with thicknesses below 200 nm fail by intergranular fracture at elongations of only a few percent. Thicker films rupture by ductile transgranular fracture and local debonding from the substrate. The failure strain for transgranular fracture exhibits a maximum for film thicknesses around 500 nm.
